8 Claims.

This invention relates to an improved funnel uide mounting. More particularly the invention relates to a mounting for the funnel through which filamentary ,material,.produced in vaccordance with the viscose .process, .for example, may be led into a spinning bucket in which it is collected in the form of an annulus.

The invention is concerned especially with funnel mountings of the type shown in Rushton 1,672,691. adapted to swing the funnel into operative position in the spinning bucket, and to swing the funnel clear .of the bucket when a cake ogtfilamentary material collected therein is ready vfor dofling.

L'I'hetypeof mountingof which the present invention visanimprovement comprises a support adapted .to be secured to the traverse rail of a spinningmachine, means for holding the funnel, and twoparallel ,pairs of arms arranged between thevsupport and funnelholding means; and piviotally connected to each of them. In funnel mountings of the general type described which have .been available prior to the present invention,.the arms connecting the support and funnel holding means have been pivotally mounted on thesupport and holding means by pivots which also constitute part of the means for adjusting the tightness of the joints between the arms and connected parts. In addition, such adjusting means have been located in exposed positions 1 where they have been subject .to-zcorrosion by the acid escaping from the spinning machine.

Experience has shown that because of the corrosive efiects of theeacidin the neighborhood of theQmachine, thejoints of the funnel-mountings become stiff and unworkable after only short periods of use, and require constant readjustment. Further, since the pivots and adjusting means are interdependent, the constant swinging of the arms on their pivots has a loosening effect on the joints so that even when the parts are not corroded, retention thereof vin a predeterminedtightbut relatively movable condition requires constant readjustment.

It is a-primary object of the present invention to .providea swingable tunnel mounting which functions smoothly and maintainsits tightness at all times-over long periods of use. Another object :is to provide a funnel mounting of the type described in which the means for tightening the joints is independent of the pivotal means connecting the pairs of parallel arms to the support and. to the funnel holding means. A further object is to provide a stream-lined funnel mounting in which the number of exposed movable 2 parts is reduced. Other objects and advantages of the invention will be apparent from the following description whenread in conjunction with the accompanying drawing, inwhich Figure 1 is a side elevation of the improved funnel mounting, in which the operative position isshown in solid lines, and the inoperative posi- .tion is shown in broken lines; v

Figure 2* is a plan view of the improved mounting; and

Figure 3 is a view taken on line III-III of Figurer2.

In the drawingthere is shown a portion of a spinning bucket .2 provided with a cover v3. A traverse rail 4 is provided to impart relative vertical reciprocal movement between the spinning bucket i2 and the .funnel guide 5 for-laying the: filamentary material in a .series'of layersagainst the inside wall of thevbucket. The filamentary material is introduced into the bucket through funnel .5 having a stem '6 extending into the: bucket through aperturelin cover 3. The .holdingmeans for the guide 5 comp-risesa threaded bushing l2, an extension .9 of a movable member 10, and, the nuts 8 for .adjustably holding the guide and bushingin fixed position on the extension 9. .Secured to traverse rail 4 by bolts l3"i's.a support 14. Support 1.4 is connected with movable member ill of the funnel holding means by twopairs of arms 15 and "5 arranged in parallel relation one ,pair above the other, each pair of armsbe'ing pivotally connected to support l4 and movable member "Ill by'means of pivot pins 11. The pivot pins project from the inner faces 7 of the arms into bores ,insupport I4 and member to, so that when the device is assembled, the pivotrpins are entirely enclosed within the arms and support 14, and within the arms and member 0,. The two arms constituting each pair are adjust'ably joined together by shouldered studs f8 Whichscrew into threadedholes 19 in the inner faces of the arms. .The ends of the studs are threaded oppositely that is one end is left-hand and the other right-hand so that turning of the knurled portion intermediate the shoulders tightens or loosens the connection between the stud and the pair of .arms. -Gaskets 20 may beprovided between the arms and the shoulders of studs 18. Studs l8, which in cooperation with the threaded holes in'the sides 'of the arms, afford a ready means of simultaneously adjusting the relation of the two arms 15 and the two arms It as to set the joints in any desired tightness, are disposed intermediately of and independently of the pivot pins l1 whereby the arms are connected to support l4 and member ID. The studs are readily available for adjustment by the operator. The pivotal movement of the arms on the support I and member In of the funnel holding means does not affect the studs or exert friction thereon, causing undue wear or loosening thereof, and the parts are retained in the adjusted position until changed by the operator. The pivot pins which are entirely enclosed within the arms and support l4 and member ID, are not effected by acid escaping from the spinning machine, so that the arms remain freely swingable over an indefinite period of time and the funnel mounting does not become stifi' or unworkable. The funnel mounting may be constructed in its entirety of any suitable acid resisting material, such as a resinous material of the type of Bakelite or Durez, for instance and, preferably, pivot pins are molded or otherwise formed integrally with the arms l5 and I6.

Modifications may be made in the apparatus disclosed herein without departing from the spirit and scope of the present invention which is not to be limited except as necessitated by the appended claims.
